MILLED POST CONSTRUCTION Application filed May 26,

This invention aims to provide a novel means whereby the plates of a variable condenser may be assembled with the posts of the condenser.

It is within the province of the disclosure to improve generally and to enha co the utility of devices of that type to which the invention a ppertains.

Vith the above and other objects in view, which will. appear as the description proceeds-1, the invention resides in the con1- bination and arrangement of parts and in the details of eonstructiol'i hereinafter described and claimed, it being understood that, within the scope of what is claimed, cl'ianges .in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings liiguri-i 1. shows in end elevation, a device (JOIlStIHCtO/Cl in accordance with the invention; F i gure 2 a plan; Figure 3 is a section on the line 3-3 ot Figure 2; Figure is a iraginental section taken longitudinally of one oil the posts.

The parallel metal posts of a variable condei'iser are shown in the drawings and are marked by the numeral 1., the posts being O'l i hexa i onal cross section, if desired, and being n-ovided with, transverse notches 2 which extend ilive-sixths of the way around the posts, that is, one of the (lat outer surfaces of each. post is not intersected by the notches. The notches 2 form bridges 3 in the post, the outer surfaces 4 ot the bridges coinciding with one of the flat longitudinal surfaces 5 of the posts. The side surfaces FOR VARIABLE CONDENSERS.

The bridges 3 extend, in a direction at right angles to h alt way their outer surfaces l, more than across the post 1, as clearly shown in Figures 3 and 4. The metal plates of the condenser and are 0 anl trict are marked by the numeral 8 it such a thickness as to fit closely ionally in the notches 2 of the posts 1, the plates having seats or notches 9 in their bridges 3.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
